HP Officejet Pro 251dw Printer series - Manual (Page 58)

Check the HP software installation
If the printer is turned off when printing, an alert message should appear on your
computer screen; otherwise, the HP software provided with the printer might not be
installed correctly. To resolve this, uninstall the HP software completely, and then
reinstall the HP software. For more information, see Uninstall and reinstall the HP
software.
Check the cable connections
•
Make sure both ends of the USB cable or Ethernet cable are secure.
• If the printer is connected to a network, check the following:
◦
Check the Link light on the back of the printer.
◦ Make sure you are not using a phone cord to connect the printer.
Check any personal firewall software installed on the computer
The personal software firewall is a security program that protects a computer from
intrusion. However, the firewall might block communication between the computer and
the printer. If there is a problem communicating with the printer, try temporarily
disabling the firewall. If the problem persists, the firewall is not the source of the
communication problem. Re-enable the firewall.
The printer prints slowly
Try the following solutions if the printer is printing very slowly.
•
Solution 1: Use a lower print quality setting
• Solution 2: Check the ink levels
• Solution 3: Contact HP support
Solution 1: Use a lower print quality setting
Solution: Check the print quality setting. Best and Maximum dpi provide the
best quality but are slower than Normal or Draft. Draft provides the fastest print
speed.
Cause: The print quality was set to a high setting.
If this did not solve the issue, try the next solution.
Solution 2: Check the ink levels
Solution: Check the estimated ink levels in the ink cartridges.
NOTE: Ink level alerts and indicators provide estimates for planning
purposes only. When you receive a low on ink message, consider having a
replacement cartridge available to avoid possible printing delays. You do not
need to replace the ink cartridges until prompted to do so.
